abstract = "For the \first time, in situ turbulence measurements
collected in the vicinity of theBrazil-Malvinas Con\fluence
are used to determine the in\fluence of the ocean waves and
atmosphericstability on the Marine Atmospheric Surface Layer. From
the analysis of 187 high-frequency sampledsegments of temperature
and wind velocity, carefully selected from three ship campaigns of
the Air-SeaInteraction at Brazil-Malvinas Con\fluence
project, we found a particular behavior of the drag
coe\fficient,with a negative trend for a calm wind speed up
to 10 m/s when the signi\ficant wave height was lower
than2.5 m, and a continuous decrease of the drag
coe\fficient with increasing wind speed for
signi\ficant waveheight higher than 2.5 m. The results
suggest that waves ac t as roughness elements during high
waveconditions, inducing a zero-plane displacement in the order of
0.1 to 1 m as an indication for awave-induced roughness layer. In
addition, the analysis of the turbulent kinetic energy (TKE)
budgetindicates the occurrence of upward TKE transport mainly
during stable conditions, while the generalpatterns of transport
and dissipation of TKE are similar to observations taken over land
surfaces.",
